Tech lead Embedded Software Engineer

Loop Future; Lisboa; On-site; EUR 55,000 - 75,000; Full time

Job summary

Loop Future seeks a mid-senior Embedded Software Developer to design object-oriented software for embedded and constrained systems, working close to hardware with Embedded Linux. You may work with RTOS or PC-side C#/.NET applications, depending on the project.

You will build secure, Yocto-based Linux distributions, integrate hardware interfaces, and implement encryption and secure boot. Leadership of the embedded team is part of the role, offering a challenging opportunity in Lisbon, Portugal.

Qualifications

• 7+ years of relevant software engineering experience, ideally in embedded, low-level or hardware-constrained environments.
• Strong hands-on C++ experience and solid object-oriented programming knowledge.
• Experience with Embedded Linux.
• Experience with secure communication protocols such as TLS/HTTPS; gRPC exposure is highly relevant.

Responsibilities

• Develop and maintain C++ software for embedded and constrained systems, using strong object-oriented principles to define classes, interfaces and interactions between components.
• Build and secure Yocto-based Linux distributions, ensuring a minimal attack surface and protected boot cycles.
• Integrate hardware interfaces and communication buses such as SPI, I2C and UART, taking memory, CPU and platform constraints into account.
• Integrate security controls such as encryption (AES, RSA), Secure Boot, and Hardware Root of Trust (TPM/HSM).
• Develop, test and debug software in Linux, Eclipse and VM-based environments, contributing to system integration and validation.
• Manage the embedded software engineer team.
